What is Barrier Banking?
The Salmon DNA Australia method
Make the deposits every day, so your skin can afford the withdrawals.
The definition
Barrier Banking is a daily skincare habit of making small, steady deposits into your skin barrier, a gentle salmon DNA cleanse, serum, a moisturiser that locks moisture in and daily SPF, so your skin holds up and looks its best on the days that take more out of it. The term was coined in 2026 by Sam Thompson, founder of Salmon DNA Australia, the official Australian and New Zealand distributor of CureNex and Vitaran.
Deposits and withdrawals
Your skin barrier is the outer layer that locks moisture in. Some days add to it. Some days take from it.
Withdrawals
Aircon and heaters. Long flights. Late nights. Hot showers. Summer sun, salt water and chlorine. Harsh scrubs. Peel week.
Deposits
A salmon DNA cleanse that does not strip. A salmon DNA serum. A moisturiser that locks it in. SPF every morning. Masks and eye patches when you need a top up.
What a strong skin barrier does for your skin
- Locks moisture in, so skin feels less tight and dry.
- Helps keep everyday stressors out: aircon, sun, wind and pollution.
- Smoother, softer texture you can feel.
- A plumper, bouncier look, with fine lines looking softer.
- Clearer, more even looking skin.
- That lit from within glow, because smooth, hydrated skin reflects light.
- Makeup sits better, so you need less of it.

Barrier Banking questions
Is Barrier Banking a treatment?
No. It is an everyday care habit that helps skin stay hydrated, soft and healthy looking. Our products are cosmetics. If your skin is irritated or broken, speak with a health professional.
How long until I notice a difference?
Banking is about consistency. Give a steady routine at least four weeks to judge how your skin looks and feels.
Who created Barrier Banking?
Barrier Banking was coined by Sam Thompson, founder of Salmon DNA Australia on the Gold Coast, the official Australian and New Zealand distributor of CureNex and Vitaran Korean skincare.
